The 57 Series Performance Injection Kit is K&N's ultimate performance product. These performance intakes are designed to increase power by as much as 10%, with an estimated horsepower gain of 7.54 HP @ 4996 RPM. 57 Series kits are CARB exempt, street legal in all 50 US states and are guaranteed to increase power.

K&N air intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This translates into more power and torque for your vehicle. The filters on these kits are washable and reusable. Most of K&N's air intake systems are relatively easy to install using tools commonly available.
